How To Choose

Researching Electrical Contractors in Marin County

Electrical work concerns homeowners more than most other types of home improvement projects and repairs. That’s understandable since electricity can be dangerous to deal with and can pose serious safety hazards if the job isn’t done right.

That’s why it’s essential to hire an experienced, licensed electrical contractor who knows how to install and repair electrical systems to code.

Expert electricians will be able to accurately diagnose problems, including those withfaulty home wiring, electrical systems, overloaded circuits and electrical panels. They’ll also be able to help you navigate your options for repairs, rewiring, new electric installations and other necessary repairs and new installations.

Researching your options will make it possible for you to find the electrical contracting firm that best fits your needs among those in the major Marin County cities of San Rafael, Mill Valley, Larkspur, Sausalito, San Anselmo and Novato and those in the smaller towns.Additional Information on Local Electricians in Marin County
Electrical emergencies and large electrical installation projects aren’t good times to try out new electricians. So it’s wise to interview and hire an electrician for a few small jobs before you need them for a last-minute fix or major project. That way, you’ll be able to see the quality of work and level of service your contractor provides without a large commitment.

When electrical problems arise or when you’re planning a large rewiring project or home addition, you’ll have confidence calling that electrician back again to do a larger, more in-depth job.

Keep in mind that cost shouldn’t be the deciding factor in which electrician you choose, unless all the other factors are equal. An electric contractor’s experience, skill, the quality of materials and ability to work to code are far more important than hourly rates.

Higher quality electricians in Marin County and the Bay Area may charge more for their services at the outset, but their experience may allow them to finish the jobs faster, complete them with more accuracy and provide a safer and more attractive installation and repair than less experienced electric services.

Industrial and Commercial Electrical Contractors in Marin County
Commercial electricians are those that do not work in residential settings, and instead provide electrical repairs and installations for commercial buildings including offices, stores, hospitals, public buildings and government buildings.

Likewise, industrial electricians are those who specialize in industrial electrical installations and repairs. Industrial and commercial electrical contractors may also create and install power generators and power systems, upgrade existing electrical systems, deal with high voltage wiring and troubleshoot electrical system failures.

It’s important to remember that residential and commercial electricians are licensed to perform different tasks and have different experience, so it’s wise to hire the company and professional who best can deal with your specific electrical needs.

You are the customer. If your goal is to choose an electrical contractor that will deliver high customer satisfaction and quality, you’ll feel confident in choosing a Diamond Certified electrician. Each has been rated Highest in Quality in the most accurate ratings process anywhere. And you’re always backed by the Diamond Certified Performance Guarantee. Here’s why the Diamond Certified ratings and certification process will help you find a top-rated electrician and is unparalleled in its accuracy, rigor and usefulness:

2) Statistical Reliability: A large random sample of past customers is surveyed on an ongoing basis so the research results you see truly reflect a Diamond Certified company’s top-rated status.

3) Full Disclosure: By clicking the name of a company above you’ll see the exact rating results in charts and read verbatim survey responses as well as researched articles on each qualified company.

Joe Greenwood: An Electric Opportunity

By James Florence, Diamond Certified Expert Reporter

SAN RAPHAEL — While working as a laborer on a construction site, Joe Greenwood was presented with an unexpected opportunity that eventually led to a lifelong career. “When I was 18 years old, I was working for a general contractor as a jack-of-all-trades, doing everything from painting to carpentry,” he remembers. “One day, we had an electrician on site—a man I knew from church named Al. Out of the blue, Al asked if I’d be interested in apprenticing with him to learn to be an electrician. I replied, ‘Sure, I’d love to.’”

Following his apprenticeship, Joe gained further experience by consecutively working for three different electrical contractors. While most people would’ve struck out on their own at this point, Joe instead decided to increase the depth of his industry knowledge through formal education. “I was thinking about going into lighting design and sales, so I went back to college and majored in managerial psychology,” he explains. “After earning my degree, I considered going back to get my master’s degree, but I was so wiped out from the previous couple of years that I decided to take a break from school. Soon after, I got my license and started my own electrical company in 1991.”

Today, as owner of Greenwood Electric, Inc., Joe says his favorite part of his job is giving people a better impression of his industry. “Like many trades, the electrical industry often gets a bad reputation, which is why I love working with my customers and gaining their trust. By providing excellent service, I hope to leave each of my clients with a positive feeling about their interaction with my company.”

A lifelong resident of Marin County (where he lives with his wife, Cara), Joe expresses his appreciation for the well-rounded character of the Bay Area. “I like living in the San Francisco Bay Area,” he affirms. “It’s diverse and forward-thinking, and there’s always something going on.”

Outside of work, Joe spends as much time as possible at high altitudes. “I’m a pilot and fly as often as I can—usually on the weekends, but sometimes during the week if I get a chance,” he explains. “I fly both a single-engine and multi-engine airplane, and I’m currently in the process of earning my commercial rating.” Joe also enjoys playing golf, going on mountain hikes with his dog, Beau, and hanging out with family and friends.

In regard to his personal career, Joe espouses the importance of taking care of both his customers and himself. “I treat my customers the way I’d want to be treated, which is why I make it a priority to return phone calls, listen to their needs and give them what they want,” he says. “However, I also make it a point to take care of myself. Running a small business is pretty much non-stop, but there are times when I need to take a break and re-energize. That way, I can make sure I have enough energy to give my customers the best possible service.”

When asked the first thing he’d do if he could retire tomorrow, Joe says he’d take his aviation avocation to new heights. “After I earn my commercial rating, the next thing I want to do is become a Certified Flight Instructor and get into teaching. So, if I were to retire tomorrow, I’d probably redirect all my efforts toward that goal and start passing my piloting knowledge and experience onto others.”

Jerry Thompson: Electrical Integrity

By James Florence, Diamond Certified Program Reporter

SAN RAFAEL — When Jerry Thompson was 18 years old, he wasn’t sure which direction his professional path would take. Fortunately, with a little paternal guidance, he was able to forge his way to a successful career. “I got involved in the electrical trade through the encouragement of my father,” he explains. “When I graduated high school, I wasn’t sure what I wanted to do. My father was an electrician, and he said the trade had done him well and encouraged me to take the exam for an electrical apprenticeship. I took his advice, passed the exam and, within a couple of years, began my apprenticeship. From there, I worked my way up to journeyman status and eventually founded my own company in 1993.”

Today, as owner of Integrity Electric, Inc., Jerry says his favorite part of his job is receiving positive feedback from happy customers. “Besides enjoying the work itself, I like the fact that people are thankful when we finish. When you restore power to someone’s home after an outage, they’re generally very appreciative, which feels good.”

Originally from San Francisco, Jerry currently resides in Novato with his wife and business partner, Kari. “Living and working in Marin County has provided us with a lot of great opportunities,” he says. “I appreciate the fact that the economy has enabled us to expand even in the face of a recession. I also like not having to cross too many bridges to get to work.”

Outside of work, Jerry engages in a variety of active pastimes, from playing drums to swimming. “I play drums in my church worship band, as well as in a local group called Factor 11. I’m also on the swim team at Rolling Hills Club in Novato.” In addition to his personal hobbies, Jerry enjoys spending time with Kari and their two daughters, Isabelle and Danielle, whether going on ski trips or solving jigsaw puzzles together.

In his life and career, Jerry espouses the importance of being present when opportunity knocks. “Woody Allen said, ‘80 percent of success is showing up,’ which I definitely agree with,” he says. “Even if you’re just starting out and don’t know anything, if you simply show up, have a good attitude and give your all, you’ll be surprised how far you can go. On the other hand, a good attitude won’t make much difference if you don’t seek out opportunities to succeed.”

When asked the first thing he’d do if he were to retire tomorrow, Jerry says he would do some traveling before returning to give back to his community. “I enjoy travel, so I’d spend about a year roaming the planet. After a while, however, I think that would lose its luster and I’d want to get involved in something more rewarding, like charity work. I think I have a gift for service, so I’d probably devote some of my time to volunteering in the community.”

Ask Me Anything!

Q: What’s your favorite sports team?
A: The San Francisco 49ers.

Q: Do you have a favorite board game to play with your family?
A: Besides jigsaw puzzles, we like games like Sorry and Monopoly Deal, which is an offshoot of the original Monopoly.

Q: What’s your favorite type of food?
A: Thai.

Q: If you could immediately master any musical instrument, what would you choose?
A: If I could play harmonica like John Popper, I would be really happy.

Chet Heenan: From Firing Up to Wiring Up

By James Florence , Diamond Certified Resource Reporter

ROHNERT PARK — As a chef-turned-electrician, Chet Heenan went from firing up ovens to wiring up electrical systems. “When I was a young man, I worked as a chef at a restaurant,” he recounts. “However, even though I had a job, I found it difficult to make ends meet, so I decided to answer an ad in the newspaper for an electrical apprentice. After landing the apprenticeship, I spent a couple of years training with an electrician by day and working as a chef by night. Once I became proficient in electrical work, I moved to make a full-time career out of it. Eventually, I ended up at Reyff Electric, which is where I’ve been for the last 11 years.”

Today, Chet says his favorite part of his job as a service manager is its rewarding nature. “What I enjoy most is being able to help people. Whether it’s assisting a senior citizen or seeing the look on a customer’s face when we turn on their revamped lighting for the first time, there’s a great feeling that comes from impacting somebody’s life, even if it’s in a small way.”

A lifelong resident of Forestville, Chet expresses his appreciation for the versatile landscape and lifestyle of West Sonoma County. “You can take me out of the country, but you can’t take the country out of me,” he laughs. “I really like the wide variety of landscape features here, from the redwoods to the vineyards to the Russian River. It’s fun to just explore and enjoy everything we have access to.”

Outside of work, Chet spends his time outside of work engaged in hobbies like cooking and reading. “I’m not a professional chef anymore, but I still do a lot of cooking to keep my skills sharp,” he says. “I’m also an avid reader of all types of books. To me, it doesn’t really matter what a book is about as long as it’s well-written.” When he’s not preparing food or absorbed in a novel, Chet enjoys hanging out with family and going on walks with his Australian Shepherd, Sadie.

In regard to his professional career, Chet espouses the importance of customer care. “When Ray Reyff first hired me, he told me his goal was to create lasting customer relationships, not just get wealthy off of one client. In his mind, the company’s purpose wasn’t to make as much money as possible—it was to provide a valuable service to the community. Since then, I’ve tried to apply those values in my daily work by keeping our customers’ best interests at heart.”

When asked the first thing he’d do if he were to retire tomorrow, Chet says he’d dust off his chef’s hat and revisit his former livelihood. “I still have a passion for the culinary arts, so if I were to retire and had some money, I might open a restaurant—maybe a steak and seafood place with some French and Caribbean fusion going on.”

Ask Me Anything!

Q: What’s your favorite kind of food?
A: Mexican.

Q: What’s your favorite local restaurant?
A: Happy Dog in Sonoma. It’s kind of a guilty pleasure, but if you ask me, they make the best double cheeseburger anywhere.

Know What You Want

Know What You Want from Marin County Electricians

When beginning your search for a good electrician, start by asking yourself a few basic questions about the work you need done and the type of contractor you want to hire. Write down your answers as having specific goals can help you present a coordinated case to the companies you interview. Here are some sample questions to get you started:

Do I want a Diamond Certified electrical contractor that is rated highest in quality and backed by the Diamond Certified Performance Guarantee?

What services do I need (electrical repairs, home rewiring, commercial electrician services, new construction electrical work)?

What is my budget for my home electrical installation or repairs?

Are there any job specifics that I or the contractors will need to take into account when planning the electrical repairs or service? (i.e. old wiring, the location of the wires to be replaced or repaired, etc.)

What professional qualities and characteristics do I want in a Marin County electrician? These may include timeliness, cleanliness, good communication skills, knowledge base, experience, and follow-up service.)

What To Ask In Person

Questions to Ask Electricians in Marin County in Person

Will I be able to stay in my home during the rewiring? Or will the electricity be shut off for too long for me to remain comfortably in my home?

Have you completed similar electrical work in my area of Marin County?

Do you have a list of recent customer references that I can call?

How do you finish your electrical installations and repairs? Is it possible for you to return my home to the condition it was in before you did the work, or will I need to hire another contractor to repair walls, paint or other areas?

How should I handle future electrical service issues? Will you be responsible for warranty work if there’s ever a problem with my new electrical wiring and fixtures?

Is there anything I can do to make the electrical repairs and installation process go smoother?

What To Ask References

Gain Insight from References of Marin County Electrical Contractors

It’s best to choose a Diamond Certified electric contractor because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from an electrician in Marin County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

If you can’t find a Diamond Certified electrician within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your contractor. Keep in mind, though, that references provided to you by electricians are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

Were you satisfied with the service from _(electrical company name)_?

What was the type and scope of job they did for you (emergency electrical repairs, electrical rewiring, lighting installation, fuse replacement, electrical panel service, etc.)?

Were they prompt and personable?

Did the electrician explain to you the statusof the work?

Did they complete the work on time?

Were there unexpected costs? If so, what were they for and were they avoidable?

Did the electricians charge extra to travel to your home if you live in a smaller Marin County town such as Almonte. Strawberry Point, Olema, Santa Venetia, Dillon Beach, Bolinas, Marin City, Lucas Valley, Black Point, San Geronimo or Tamal?

Did the electrical contractors clean up after finishing the job?

Would you recommend their services to friends or family?

When you need electrical service in the future, will you hire this company again?

Review Your Options

Find and Hire Good Electricians in Marin County

The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

There are many good electrical contractors in the major cities of San Rafael, Larkspur, Novato, Mill Valley, Fairfax, San Anselmo, Tiburon, Corte Madera, Sausalito and Ross. Hiring a professional who does quality work and has experience in the services you need can mean a better chance of getting the results you desire. So before deciding on the best electrical contractor for you, mull over the following questions.

Is there an electrical contracting company on your list that can meet your needs for electric services, supplies and materials, brands and installation or repair requirements?

Are the Marin County electricians knowledgeable about the repairs and new electrical wiring you need? Can they easily explain to you which products and brands best fit your needs?

Is the contractor sensitive to your budget? Can they give you varying bids that address your resources?

Do the electricians guarantee their work and offer warranties on their products?

How To Work With

Before You Hire A Good Electrician in Marin County

Some individuals like to establish a relationship with their electrician by hiring them for smaller projects before calling them for emergencies and large electrical installation projects. But just like homeowners can be choosy about with whom they do business, many contractors are interested in providing services to those who are reliable, fair and honest. Bids can be expensive to prepare and no contractor wants to waste time bidding a job that homeowners aren’t serious about finishing.

How can you be the kind of homeowner that the best electricians want to work with? See the tips below.

Prove your interest in good value, not just the lowest bid. Many people start their discussion with contractors by asking simply about price, not value. You can show your interest in quality by asking questions about products, repair methods, installation techniques, warrantees and lasting value rather than simply price.

Be upfront with the contractors that you’re interviewing if you’re accepting multiple bids. But only shop among carefully-selected companies that offer quality work and don’t accept more than three bids.

Tell your contractor exactly what you want done and every specific direction or request you have. This will allow them to give you the most accurate bid possible and gives them insight into exactly what you want from your contractors. If they can’t provide what you need or want, it’s better to find out before you’ve wasted your time and theirs.

Interview and choose among local electricians in Marin County. Most electriciansprefer to work within a smaller radius, as this allows them to provide faster service and reliable emergency repairs.

Now That You’ve Found Your Marin County Electrical Contractor
Now that you’ve found the electrician that best suits your needs, you can move forward and sign a contract. Good contracts should include details about the scope of the electrical work, any materials and products to be used, payment terms, the expected timeline for the job and any warranties and guarantees that will cover the work.

Your electrician should provide the contract to you and allow you to read through it and ask any questions you may have before signing the contract. This agreement protects you, your property and the contractor, so it’s important that you understand all terms and exclusions and that you never sign an incomplete or blank estimate or contract.

If there are items you verbally agreed upon with your electrical contractor, you may write in those terms. These may include specific expectations and instructions, expected start and end dates, clauses that stipulate when the work must be completed, and any bonuses or offers you wish to extend for early completion of the work.

Be a Good Customer

How to Help Your Marin County Electrical Work Go Smoother

There are a few things you can do before your electrician arrives and while they’re working in your home or business in order to help the work move along more smoothly.

Have a list of specific repairs or electrical installation work you need done, and write down any questions or concerns for your Marin County electrician. This will ensure you get the service and answers you need and can possibly cut down on the length of time the job takes, reducing billable hours.

Clear unnecessary items from the area where the contractor will be working. For example, if your electrician will be repairing or installing a new electrical panel, make sure he or she has easy access to the existing panel by moving furniture or other objects that are in the way. This will cut down on the amount of time your contractor has to spend clearing the area in which they’re working.

Keep pets and children out of the area while the work is ongoing. For larger projects that take more than one day, such as house rewiring, your electrician may have to leave wires exposed or walls opened. In this case, keep family members and pets out of the room until the work is completed. Talk with your electrical contractor about the duration of the job and his or her preferences.

Ask your electrician company representative what you can do to help speed the job along or make the work easier. There may be simple steps you can take to increase the contractors’ efficiency, thereby cutting down on the amount of time spent and the overall cost of the job.

How Can You Be a Good Electric Contractor Customer?

It’s the electrician’s responsibility put in quality wiring and electrical fixtures using the best possible installation techniques. But you play a big part in the success of your electric services, too. Here are a few simple steps you can take to be a good customer when hiring a Marin County electrical company.

Be clear and upfront with the electrical contractor. Let them know what you want from your electrical work, the long-term outcome you’re expecting and specific ways they can satisfy your expectations.

Remember, a friendly smile and good attitude goes a long way.

Before you hire a contractor, restate your expectations and goals, and reiterate to the company representative your understanding of the agreement. Most problems with local electrical contractors occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.

Ask your electric contractor if you should call to check on the progress or if he will call you with updates.

Be sure your service representative has a phone number where they can reach you at all times. The electrical work will move along more smoothly if the electricians can reach you for with updates, questions and authorizations.

Why would you want to be a good customer? Electricians in Marin County including those in the larger cities of San Rafael, Novato, San Anselmo, Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax, Ross and Mill Valley appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship.

Check The Work

Check all Electrical Repairs and Installations Against the Invoice

When your electrical services are complete, ask your electrician to give you an invoice and walk you through the work before they leave your home or business. An invoice usually includes the following:

The electrical contractor’s name, business address and license number.

An itemized list of all electrical work performed.

A complete list of all electrical supplies used, including new parts and replacement parts.

The total cost of the job, broken down into amounts due for electrical parts, wiring and for labor.

Any applicable guarantees and warrantees provided by the electrical equipment manufacturers and the installers.

Use the information on the invoice to compare against the work that was actually completed. If items don’t match up or you have questions about what was done, ask your electrician before they leave the property. During your walk-through, ask about any special instructions for operating or maintaining your new electrical installations.

Top 10 Requests

Top Service Requests of Plumbers in Marin County

There are many electrical services required of electricians in Marin County. The following are the most common electrical repairs and installations.

Electrical Wiring/Rewiring
Electrical wiring is a system of insulated wires that carry electricity from the electrical source to outlets and fixtures in homes and buildings. Sometimes referred to as building wiring, electrical wiring and rewiring services.

Wiring for new outlets and outlet wiring replacement is very common. Many homeowners believe they can install new outlets, test for outlet wiring problems or install switch boxes, but even these minor electrical repairs are best left to professionals. Outlet wiring is a fairly simple procedure that will take most electrical contractors just a short time. However, outlets that are wired incorrectly can cause electrical shocks and even fires, so it’s imperative that you hire a good electrician to do your electrical work.

Install Ceiling Fans
Ceiling fans can reduce your heating and cooling bills and keep your house more comfortable year round. Ceiling fan installation is a common procedure that can be quick or require rewiring, depending on the desired location. Before calling a Marin County electrician to install your new ceiling fan, know where you’d like the fan located and whether you want a ceiling fan with a light. You may even want to purchase a new ceiling fan for installation.

Residential Electrical/Home Wiring
Most residential electrical wiring and new home wiring projects require strict adherence to local codes. Your electrician will most likely need to pull a permit for wiring due to the potentially dangerous nature of the work, so make sure you consult your contractor. New home wiring can be done to replace old wiring, faulty wiring or frayed wiring. It can also be installed as home wiring upgrades.

New Construction Electrical Services
New construction electrical services are those wiring and electrical system installation services for new buildings, including new homes, commercial buildings and industrial facilities. These wiring services are provided while the buildings are still in frame-up stages rather than after the walls have been put up.

Home Wiring Repair
Frayed wiring, faulty wiring and old home wiring may need to be repaired. When wiring replacement or rewiring isn’t required, a simple home wiring repair may be possible. Your Marin County electrical contractor will repair existing wiring to make it safer and more reliable.

Electrical Maintenance
Electrical maintenance is the term for all steps taken to maintain, preserve and upkeep electrical equipment and systems. Many homeowners, business owners and industrial facility managers rely on electrical maintenance contractors. Electrical maintenance is common for power outlets, electrical generators, surge protectors, lighting replacement, electrical energy savings upgrades, electrical inspections, electrical assessments and preventative maintenance for electrical systems

Electrical Inspection
All new electrical installations and many electrical repairs are required to pass an electrical inspection. Most residential electrical permits require three inspections. One during the early stages, one mid-way through the work and a final inspection. Your electrical contractor may be responsible for calling for inspections, so verify with them who will take on this aspect of your home electrical installation project. This inspection verifies that all work is done correctly, safely and according to local electrical codes in Marin County.

Electrical Repair
Common electrical repairs in Marin County include wall switch troubleshooting, electrical rewiring and electrical wiring repair, circuit breaker troubleshooting, ceiling light fixture repair / replacement and electrical outlet repair. Safe and legal electrical repairs must be done by a licensed, insured electrical contractor who is in good standing with the state.

Q: Can I do home electrical work myself?
A: Any kind of home improvement project poses risks to homeowners who are trying to do it themselves. But none carry such a great risk as electrical work. Inexperienced people should never try to install electrical wiring or repair electric systems. Instead, all work should be performed by a licensed, experienced electrical contractor. That’s because professional electricians are trained in safety and code requirements, they’re better equipped with the correct tools and materials to complete the job, and they have the skills and experience to complete the job efficiently.

Q: When should I call an electrician about maintaining or upgrading my home’s electrical system?
A: It might be time to call a local electrical contractor if you frequently blow circuits or fuses, your lights dim when you turn on your air conditioner or other appliances, your lights flicker or go off and on, you smell electrical burning/wires or fuses smell hot, you use multi-plug power strips because you don’t have enough outlets, you use two-pronged adapters with three-pronged plugs or you often use extension cords.

Q: What do electrical repairs and installation cost?
A: Some contractors give hourly rates or per-project costs over the phone, but many decline to give estimates over the phone without seeing the project first. That’s because many jobs aren’t as simple as they may appear and homeowners may not be able to accurately describe the problem over the phone. Good electricians often want to see the electrical system themselves before they go on record with a price, because they don’t want to give inaccurate estimates.

Q: What should I do if my power goes out?
A: If the power is out throughout your home, check with a neighbor to see if they have power. If they are experiencing a power outage, call your utility company to report the problem. If the power outage seems to be affecting only you, call your electric company and ask them to send a representative to check your power supply. If you still are experiencing a problem, if the power company is unwilling or unable to send a representative, or the power is only out in one area of your home, call a local electrician to investigate the cause.

Q: Does all home electrical work require a permit?
A: General residential electrical services don’t usually require a permit, but large projects such as additions, basement and attic finishing and garage conversions may require permits and inspections. If you fail to get proper permits and the work doesn’t meet electrical and building codes, you could be required to redo the work at additional expense.

Q: Will I be without power while my electrician is working?
A: Depending on the job you’re having done, your contractor may not have to turn off the power to your entire home. In some cases, they’re able to cut off single circuits for a short time. Larger projects and repairs may require a total shut-off, but most good electricians minimize the amount of time they leave their customers without power.

Q: Can I plug a four-prong appliance into a three-prong outlet?
A: New appliances are designed to meet the newest standards, so older appliances may not always fit new wiring and new appliances may not fit newer electrical wiring systems. Your electrical contractor can replace a new four-prong cord with a three-prong cord in existing installations. Talk with a local electrician about your specific needs.

Q: Why are some of my outlets or lights working while others are not?
A: There are several possible reasons for this, and only a licensed electrician can diagnose your specific problem. It may be that some of the outlets and/or lights are on a circuit that doesn’t work or is failing while other lights and outlets are on a working circuit. In this case, repairing the circuit can fix the problem. Another possibility is that the outlet or light switch has worn out and simply needs to be replaced. Electrical breakers also may have been tripped, and resetting the breakers may fix the lights and outlets. In any case, it’s best to call a local electrical contractor to diagnose and repair the problem.

Q: My light fixtures are flickering, what should I do?
A: Flickering lights can be a symptom of several problems. It could signal a loose connection in a circuit or a problem with the general electric supply. It’s best not to use the lights that are flickering (or any lights in your home or office if all of the lights are flickering) and call a licensed electrician to diagnose the problem immediately.

Q: What causes residential lights to dim?
A: Dimming lights are caused by several problems, which can only be accurately diagnosed and repaired by licensed electric contractors. If all of your lights dim, the problem may be at the local utility, the transformer or the service feed. Call your utility to check this first. If your lights dim when an appliance such as an air conditioner or refrigerator is turned on, the lights may be on the same circuit as the appliance and not receiving enough electricity when the appliance turns on.

This can be repaired by putting appliances that draw a lot of electricity on a dedicated circuit. Dimming lights may also be a sign that your home wiring is too small or your power source isn’t strong enough.

If your lights alternately dim and brighten, it could indicate a serious problem such as broken, loose or corroded wires. If this is the case, call an electrician right away to check your home wiring.

Q: How can I lower my electric bill?
A: The easiest way to save money on your electric bill is to monitor how often you use your heater, air conditioner, hot water heater and washer and dryer. These appliances use the most electricity and minimizing their use can greatly reduce your electric bill. Installing a programmable thermostat can help regulate your home’s temperature and cut down on wasted heating and cooling costs. Turning down your hot water heater or adding a programmable thermostat to it can help minimize hot water waste. And replacing old and broken appliances with higher efficiency appliances can save money every day. Talk with your electrician contractors for money-saving ideas that are specifically tailored to your home and energy usage.
